After you have successfully configured the audience key and SAML application, you can test activation before you activate the 3rd party IdP authentication for the entire domain. Once you activate 3rd party IdP authentication, you can begin using your 3rd party IdP to authenticate users with the selected email domain within the Infoblox services. That is, any user and portal admin with "*@*[*mydomain.com*](http://mydomain.com)" will be authenticated against the configured 3rd party IdP (your identity provider).

3rd party IdP authentication applies to all domain users attempting to access any of the following Infoblox sites: the Cloud Services Portal (CSP), SSO Portal, or Support Portal.

> ⚠️ **Note**
> ⚠️ 
> ⚠️ <span style="color: #000000">If multi-factor authentication or MFA is already activated for the selected domain, you cannot activate the 3rd party IdP until you have deactivated multi-factor authentication for that domain.</span>

<span style="color: #000000">To activate 3rd party IdP authentication, complete the following:</span>

1. <span style="color: #000000">Log in to the Infoblox SSO Portal at </span>[<span style="color: #000000">https://sso.infoblox.com/</span>](https://sso.infoblox.com/)<span style="color: #000000">.</span>
2. <span style="color: #000000">On the </span>*<span style="color: #000000">3rd Party IDP</span>*<span style="color: #000000"> page, expand the </span>**<span style="color: #000000">Activate</span>**<span style="color: #000000"> drop-down menu in the upper action bar, as follows:</span>

3. <span style="color: #000000">Click </span>**<span style="color: #000000">Activate for entire domain</span>**<span style="color: #000000"> from the drop-down menu to enable 3rd party IdP authentication.</span>

> ⚠️ **Note**
> ⚠️ 
> ⚠️ <span style="color: #000000">If after activating the entire domain, the administrator cannot log in to the SSO Portal, consider accessing the SSO Portal using the OTP (one-time passcode) to regain access and fix the 3rd party IdP configuration. For information about OTP, see </span>[*<span style="color: #000000">One Time Passcode (OTP) Access</span>*](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneCloud/pages/35397677)<span style="color: #000000">.</span>

<span style="color: #000000">To see IdP authentication in action, log in to the Cloud Services Portal or the SSO Portal with an email address in the selected domain. You should be able to see that the user is authenticated through the configured 3rd party IdP.</span>
